Toyota and other major automakers have begun scaling back production because of parts shortages from suppliers in flood-afflicted Thailand, just months after Japan’s own supply chains were decimated by a mammoth earthquake and tsunami.

The production woes stemming from Thailand’s worst flooding in five decades — which has wiped out hundreds of factories in recent weeks — come just as Toyota and others bounce back from the March 11 quake disaster that destroyed autos parts suppliers in Japan’s northeastern Tohoku region and upended car production around the world.
